MiCROSEMiA POLYGALOIDES (A. Gray) Greene, Leaflets, 1 : 89. 



1904. 

 Strepta7ithus polygaloides A. Gray, Proc. Atn. Acad. 6: 



519. 1865. 

 No. 8100, collected July 14, just outside of Grass Valley, 

 Nevada county, along the electric line leading to Nevada City. 

 It occurred in rather moist ground caused by water percolating 

 from a ditch. The type came from "very dry hillsides, in ser- 

 pentine soil, along the Tuolumne River." Without the fruit, 

 it would indeed be a difficult task to place this strange plant, 

 and Professor Greene has simplified matters by making it the 

 type of a genus distinct from Streptanthus. 



Lepidium dictyotum a. Gray, Proc. Am. Acad. "7: 329. 1868. 

 No. 7594, collected April 6, along the Santa Fe railroad 

 about a mile west of Bakersfield, Kern county. The numerous 

 plants were growing in cinders and sand on the railroad em- 

 bankment. . 



Lepidium draba L. Sp. PI. 645. 1753. 



No. 8006, collected June 9, at Yreka, Siskiyou county, in a 

 field. The species is found sparingly in ([California, being re- 

 ported only from Yreka and Berkeley, and does not seem to 

 spread rapidly. "Habitat in Germania, praesertim Austria, Gal- 

 lia, Italia." 



Lepidium flavum Torr. Pac. R. R. Rep. 4: 67. 1857. 



No. 7676, collected April 13, at Kramer, San Bernardino 

 county, where it is plentiful, prostrate on the sand among the 

 desert vegetation. A yellow flowered Lepidium is somewhat of 

 an oddity. Kramer is not far from the type locality, "sandy 

 places near the Mohave Creek."
